A horizontal bar chart displays average wages across countries for 2022, using D3 v7 to load CSV data via `d3.csv` and render SVG elements. The chart encodes numeric values with `d3.scaleLinear` for the x-axis and categorical country names with `d3.scaleBand` for the y-axis. Bars appear in steelblue, turn orange on hover, and axes are formatted with `d3.axisBottom` and `d3.axisLeft`. The data comes from a remote gist URL, and styling is handled through CSS classes.
